Rep. 82 (2011) Comments on selected forest reserves visited in SW Ghana in 2008-2010: wildlife (especially birds) and conservation status by Françoise Dowsett-Lemaire & Robert J. Dowsett Acknowledgements We are very grateful to staff of the Forestry Commission (Managers of District offices, range supervisors and others) who often went out of their way to help us with directions, personnel to guide us and other advice. INTRODUCTION All wildlife reserves in the south-west of Ghana (Ankasa, Kakum, Bia, Owabi, Bomfobiri and Boabeng-Fiema) and a few forest reserves with special wildlife value (Atewa Range, Cape Three Points, Krokosua and Ayum/Subim) were visited from December 2004 to February 2005 when we were contracted to the Wildlife Di vision (Dowsett-Lemaire & Dowsett 2005). In 2008 we started a project to study the ecology of birds and map their distribution in the whole of Ghana; in the forest zone we also paid attention to mammals and tried to as sess changes in conservation status of various reserves since the publication of Hawthorne & Abu-Juam (1995). Thus several visits were organized to the rain forests of the south-west, as follows. From 20 Nov 2008 to 12 Jan 2009 and on 9-10 Mar 2009 we visited 18 forest reserves between 5° and 7°N, covering 15 Atlas squares (of 30 by 30 min. lat./long.). With the exception of one border square (Dadieso) where we spent only 24 hours, from 3-5 days were devoted to each square, visiting one or two forest reserves per square. As far as possible we camped on the edge of forest, but sometimes could not avoid camping in farm - bush. Interviews with hunters were conducted in a few places, where the opportunity arose. From 9 Dec to 2 Jan we were accompanied by William Apraku, technical assistant for the Wildlife Division at Shai Hills, whom we continued to train in the field of bird identification. Surveys continued from 20 Nov 2009 to 1 Jan 2010, 4-19 Mar and 7-9 May 2010, completing our cov - erage of the forest region (10 Atlas squares) and extending to the peripheral forests near Dormaa and Berekum, north to Tain Tributaries II F.R. In all we visited 14 forest reserves; another two planned for this trip were not seen as they had already been destroyed (North and South Fomangsu, see below). Between 14 Aug and 4 Oct 2010, we revisited Kwei Dabanyin, Sekondi Waterworks, Atewa Range, Ayum/Subim and Opro River F.Rs. and visited two new sites: Esuboni and Amama Shelterbelt F.Rs. In 2008-10 time was also spent in the wildlife reserves of Ankasa (10 days, 16-26 Dec 2009; 5 days, 17-22 Aug 2010), Bia (8 days, 1-9 Dec 2009; 4 days, 20-24 Sep 2010), Kakum (5 days, 30 Nov-1 Dec 2008, 29 Dec 2009-1 Jan 2010, mainly Aboabo; Krua camp 24-25 Aug 2010) and Owabi (2-5 Jan 2009); Bomfobiri W.R. was revisited on 6-9 Mar 2011. An update of the bird lists for these parks is presented separately (Dowsett- Lemaire & Dowsett 2009, 2011a, b, d, e). Forest reserves are presented below, roughly in a south-north and east-west order, and are listed under 30 x 30 min. atlas squares, as this will explain the distribution maps better. In all, we made observations in about 40 forest reserves, and crossed a few others (now under plantations). Their conservation status was as sessed by Hawthorne & Abu-Juam (1995) and classified in six categories: “Condition 1” (excellent, few signs of human disturbance); “Condition 2” (good, logging restricted, <10% heavily disturbed), “Condition 3” (slightly de graded, a mixture of good and selectively logged forest, with max. 50% disturbed), “Condition 4” (mostly degraded, max. 75% heavily disturbed), “Condition 5” (very poor, little coherent canopy left), “Condition 6” (no signifi - cant forest left, or a few % in extremely poor condition). Dowsett-Lemaire Misc. Rep. 82 (2011) -2- Birds of forest reserves in SW Ghana OBSERVATIONS Takoradi square (4°30'-5°00'N, 1°30'-2°00'W) Sekondi Waterworks F.R. (10 km², Takoradi District). We camped here on 14-15 Dec 2008 (after an evening visit on 10 Dec) and again on 16-17 Aug 2010. This is situated right by the main Accra road at Sekondi (near the police barrier) and consists of a thin band of secondary forest around the dam, with planta tions of Senna (ex- Cassia ) siamea on the outside and secondary growth. Common trees around the dam include Ptero carpus santalinoides and Dialium guineense ; Baphia nitida and Hymenostegia afzelii (common in dry, semi-deciduous forest) occur in the understorey; a strangling fig belongs to Ficus lutea (= F. vogelii ). Wildlife . Despite the small size of the forest and its low canopy, some interesting birds occur here, in - cluding Congo Serpent Eagle, Latham’s Forest Francolin (both vocally active Dec, not Aug), Nkulengu Rail, Grey-throated Flycatcher, Puvel ’s Illadopsis and Tiny Sunbird, and there is a pair of White-throated Blue Swallows over the lake near the dam wall (breeding Aug); the lake is also frequented inter alia by African Finfoot and Giant Kingfisher. Black-shouldered Nightjar was heard at forest edges on both vis - its. A pair of Velvet-mantled Drongos turned up in 2010. A pair of Spotted (Greyish) Eagle Owls was on both visits very conspicuous around the dam wall, perching there before nightfall (and seen again at dawn). The forest is apparently too small to have any green turacos, and the only monkey is Green Cercopithe cus aethiops . Nevertheless this is an ideal spot close to two large towns for an evening outing, for watching some water and forest birds. Visitors have free access from 6 a.m. to 6 p.m. Conservation. The Senna plantations are exploited, most of the secondary but natural forest around the lake appears protected. Axim square (4°30'-5°00'N, 2°00'-2°30'W) Cape Three Points F.R. (51 km², Takoradi District). This is covered by Dowsett-Lemaire & Dowsett (2005). In 2006-07 the forest was also visited by B. Phalan, who added Congo Serpent Eagle, Brown-cheeked Horn - bill and Cassin’s Honeybird while Copper-tailed Glossy Starling was confirmed. In March 1989, M. Taylor had seen a male Western Wattled Cuckoo-shrike. Altogether just over 140 species have been recorded so far, excluding species of adjacent farmbush. Winneba square (5°00'-5°30'N, 0°30'-1°00'W) Proposed Kwei Dabanyin F.R. (c. 8 km², Winneba District). This is a newly proposed reserve, which we visited on 20-22 Nov 2008 and revisited on 14-15 Aug 2010. It is a good example of dry coastal forest, with such characteristic tree species as Elaeophorbia grandifolia (17 m tall, 40 cm DBH) and Croton zambesicus (20-25 m tall). The red flowers of Hildegardia barteri (Nov) are highly attractive to sunbirds. It was partly cultivated and damaged in various ways in the past, but is recovering. Canopy trees are rather scattered at present, but there is much scope for regrowth. The three commonest large trees are An tiaris toxi - caria, Ceiba pentandra and Hilde gardia ; others include Afzelia africana, Albizia ferruginea (very big) , A. adianthifolia, A. glaberrima, Cola millenii, Dialium guineense, Milicia excelsa , Millettia thonningii , stran - gling figs ( Ficus thonningii ). Some big Cynometra mega lophylla occur in an area that may become sea - sonally damp. Wildlife. Mammals include Maxwell ’s Duiker Cephalophus maxwelli and Spot-nosed Monkey Cerco- pithecus petaurista (seen), Tree Hyrax Dendrohyrax dorsalis and Demidoff ’s Galago Galagoides demid off (heard), the last two being very common throughout the forest zone. Birds (60 species recorded) include Congo Serpent Eagle (at least two pairs calling Nov), Fraser ’s Eagle Owl, Nkulengu Rail and several Puvel ’s Illadopsis; we found a nest of Bat Hawk (Nov), a rather rare raptor. Conservation. Improving and well worth preserving. Birds of forest reserves in SW Ghana -3- Dowsett-Lemaire Misc. Rep. 82 (2011) Akim Oda square (5°30'-6°00'N, 0°30'-1°00'W) Akrobong and Obotumfo Hills F.Rs (Winneba District) are some of the few small hill forests situated north-east of Winneba (near Obrachere); these cover respectively 3 and 2 km². We camped on the edge of Akrobong on 22-23 Nov and Obotumfo on 23-25 Nov 2008. These are dry semi-evergreen forests char - acterized at Akrobong by Triplochiton scleroxylon (common), Celtis spp. (incl. mildbraedii ), Cola gigan - tea, Pterygota macrocarpa ; also Albizia glaberrima, Ficus bubu, Hilde gardia, Morus mesozygia, Piptadeniastrum africanum, Pycnanthus angolensis and Terminalia superba . Hymenostegia afzelii is com mon in the understorey. At Obotumfo Ceiba is the commonest tall tree, followed by Triplochiton. On the rocky crest Elaeophorbia , Hildegardia and Milicia excelsa are noticeable, with Cola millenii and Di al - ium guineense as smaller trees, there is a very big strangling Ficus polita . Wildlife. Spot-nosed Monkeys are still present; forest guards reported to us three species of duiker (Maxwell ’s, Black Cephalophus niger and Bay C. dorsalis ) and past occurrence of Red Colobus Pilio - colobus badius .
